I am a firm believer of preventative maintenance. If the vehicle in question is in good shape, well maintained, the only parts I would consider would be a good spare tire, one that is equal to the tires on the ground. A spare generator, and fan belt, extra fuel pump and/or an electric pump plumbed and wired into the system.
I have driven my '36 Ford coupe w/59 AB engine over 94 K miles in the 71 years I have owned it, I have driven twice between Southern California and Eastern Idaho, a distance of 2,100 miles round trip, which was done none stop, seventeen hours each way, never a problem.. The only problem I have ever had with my Ford is a failed fuel pump, which I eliminated by installing an electric fuel pump.
